Pesssoallll, boa tarde !
estou com um problema serio e urgente.
eu nao consegui fazer um programa que gerasse um codigo de barras para
exibir atraves de um servlet entao comprei um em www.idautomation.com.
beleza, funcionou sem problemas no sistema windows 98 e NT, mas no linux
redhat nao funcionou.
abaixo está a copia do email que eu mandei para o suporte da idautomation.
de inicio o problema era com o xwindows, com a variavel display. beleza,
resolvi instalando um vnc.
mas depois disto apareceram erros <Font specified in font.properties not
found> quando eu executava um programinha de teste. mais abaixo está o
programinha.
o problema agora eh que eu nao sei se o problema vai ser configurar o xfs,
ou algo no linux, ou se o problema está na classe que eu comprei. Está
classe BarCode se encontra no pacote LinearBarCode.jar. O pessoal do
suporte falou q o problema nao esta na classe, pois nao utilizam a fonte
abaixo descrita.
Bom, se a resposta estiver nos dominios do java, alguem poderia me
responder?
obrigado!
//classe exemplo que esta dando erro no linux
import IDABarCode.*;
import IDABarCode.encoder.*;
class simpleGIF {
public static void main ( String [] args ) {
BarCode bc=new BarCode();
bc.code="123456789";
bc.barType=bc.CODE128;
bc.setSize(400,200);
barCodeEncoder bce = new barCodeEncoder(bc, "GIF", "newfile.gif");
}
}

I don't know what could be causing that problem. Our product does not
require use of the symbol font.
Warm Regards,
Brant Anderson
